AUTOMATIC DUMPING DEVICE.

Patented uly 31, 1917'.

Application filed September 5, 1916. Serial No. 118,503.

To all whom it may concern:

Be it known that I, HERMAN O. E. BEIN- DORF, a citizen of the UnitedStates, residing at Homestead, in the county of Pueblo and State ofColorado, have invented certain new and useful improvements in AutomaticDumping Devices, of which the following means with which the bucketdirecting means aforesaid cooperates to hold the latter maintaining thebucket'in an outwardly swung position in-relation to the well or mineshaft while the bucket is being dumped, said dumping action being. alsoautomatic in character so that the apparatus servesnot only tofacilitate the operations but to effect saving of time and'labor forcarrying on the same.

In addition to the foregoing it is comprehended to employ that type oflocking means which will automatically release the bucket directingmeans when the bucket, after dumping, is again actuated to returnit toiposition within the shaft.

T heseand such other objectsasmay hereinafter appear are attained by thenovelrconstruction, combination andarrangement of parts .to behereinafter specifically described and claimed. Reference willnow. behad to the accompanying drawings forming a part of this specification,wherein Figure 1 is aside elevation of an apparatus constructed inaccordancewith my invention, parts being broken away and showninsection; I V

Fig. 2 is a front elevation; Fig. 3 is an enlarged verticalviewpntheline -3.3 of Fig. 2;

sectional Fig. ais atop plan view. of the apparatus ands Fig. 5 isadetail view-in side elevation-of I cally;-describing the. invention, 1designates a suitable gallows frame at theupper portion of which arearranged spaced standards 2 between which is mounted a sheave3accommodating the hoisting cable 4; carrying the bucket 5. For thepurpose of convenience in this description the partsl and 5 will bereferred to as the bucket hoist. Projecting laterally from the frame 1are a pair of supporting arms 6 at the end portion of which is supported-a transverse support 7 the latter having trunnions at its, eXtremitiesjournaled in the arms 6 to permit, of rotation of said transversemember. Depending from this member 7 is a thrust arm 8 which preferablyconsists of spaced side members 9 converging at thelower extremitiesbetween which is received a friction roller 10 adapted to cooperate withthe hoisting cable in the operation of the apparatus, as will behereinafter more fully explained.

It, will be observed by reference to Fig. 1' that the arm 8 extendsdownwardly, at an incline so that the lower extremity will normally liein the path of movement of the. bucket as it is raised from theexcavation, the arm being held in suchnormal position by the stop member11 which is supported by the platform support 12.; It. will be un-'derstood that upon this last mentioned support the necessary mechanismfor mechanically operating the buckethoist may be positioned, asdiagrammatically indicated at l3.

Upon lifting movement of the bucket, hoist the arm 8 is impinged by thebucket, a cushion spring 14: being provided just above the bail of thebucket to take up the impact. After impingement as. above referred to,the arm 8 is carried upwardly with the bucket hoist moving in an are ,atone side of the gallows frame. The arm thrusts the bucket laterally fromthe frame outof the planeof its initial path of movement and whenthe armhas reached the horizontal dotted line position shown in Fig. 1 it isautomatically'engaged with a locking member 15 which is supportedbetween the lower end portions of the standards 2, as shown most clearlyin Fig. 2 of the drawings. Thelocking member l5 is held to one side soas not tointerferewith the operation of the cableby meansflof a member15 consists of the lower, hook terminal 15 and the upper curved arm 15,

said locking member normally assum ng: a

vertical position so as to lie in the path of movement of the cross bar17 carried by the side members 9 of the arm 8. This bar automaticallyengages with the hooked eX tremity of the locking member when the armreaches the horizontal position above referred to, and upon loweringmovement of the bucket toward its dumping position.

At one side of the frame is conveniently arranged the bucket dumpingmeans or platform 18 which is pivotally supported at one side asindicated at 19 and provided with a counter-balance weight arm 20. Theplatform 18 furthermore is provided'with diverging guide arms orstandards 21 so that as the bucket 5 is lowered it will be guided bysaid standards onto the platform 18. This platform is immediatelyoverbalanced and the material from the bucket thereupon dumped. Theoperation of returning the bucket to its normal excavating positioninvolves the raising of the bucket until it impinges the outer endportion of the arm 8 which is held in its horizontal position by themember 15. A continued lifting movement of the bucket hoist raises thearm 8 to the inclined dotted line position shown in Fig. 1, whereuponthe rod 17 passes over the curved upper end of the locking member 15.Lowering movement of the bucket is now free to take place inasmuch asthe rod acts upon. the rear edge of the locking member to move it out ofengaging position with respect to the rod and the arm will consequentlyreturn to its normal full line position shown in Fig. 1 as the bucket islowered to its initial position.

It will be apparent from the foregoing description that the excavatingoperation above described may be carried out by a single operatorinasmuch as the dumping operation is entirely automatic and under thecontrol of the bucket hoist. The apparatus is extremely simple in itsconstruction and may readily be used for various purposes aside fromexcavating operations, such for instance as removing material from cars,tanks or other receptacles by means of a vertically operated hoist.

Slight changes may be made in the details of construction withoutdeparting from the spirit of the invention and within the scope of theappended claims.

Having thus described my invention, what I claim as new is 1. Inapparatus of the class described, the combination with a frame andbucket hoisting means, of an arm movable incident to hoisting action fordirecting the bucket to dumping position, a hook member mounted on saidframe for free swinging move ment and engageable at one end with the armto support the same during lowering of the bucket for dumping, the otherend of said hook member being arranged for engagement by the armincident to lifting of the bucket from the dumping position to therebyshift the engaging end of said hook member out of engaging relation withrespect to the arm, whereby to effect release of the latter.
